Cameron seems quite ignorant of the fact that Cresson had ah-ead}^ described a species of this genus under the present name ; nevertheless I consider the two descriptions to apply to a single species. There is one specimen in the British Museum, taken m Brazil by Mr. Mornay about 1840. CLOSTEROCEROS, Hartig. Ber. Naturw. Ver. Harz. 1847, col. 18. In the very rare '"' Bericht natunvissenschaftlichen Verems des Harzes fiir die Jahre 1846-7," column 18, in liis " Ul3er einige parasitische Hymenopteren des Harzes," Dr. Th. Hartig apologises for erecting a ne^^- genus upon a single male specimen, found in the Claus Valley of the Hartz Mountains, and pleads in excuse its capture by the recently deceased Herr Saxesen. The descriptions of both genus and species have remained unquoted since that time ; it would be interesting to discover to ^^'hat insect they refer, and to know if the tjT^e be still extant. Hartig's description may be thus rendered : — Head \\\t\\ the mandibles apically bidentate ; labium emarginate, appendiculate, nearly orbiculate and exserted ; maxillary paipi 5-jointed, with the second and third joints longer and broader than the remauider ; labial palpi three- jointed. Antennae fusiform, with the second joint [scape] elongate and externally excised ; the eleventh to twenty-second johits incrassate and compressed (as in Euceros, Grav.), with their basal but t\^-o-t birds of theu- apical breadth. Abdomen sessile, vath the six basal segments longer than broad ; the first subri [11 sic] mose, punctate, bicarinate, parallel-sided, more than double longer than broad, with its lateral tubercles situated before the hme ; segments two to six smooth, with oblique impressed lateral lines. Wmgs with areolet as in Ephialtes manifestator. Whole facies similar to Ephialks. Great stress, as in Nees von Esenbeck's work, is laid upon the structure of the mouth-parts, which conveys nothing unusual to me ; on the other hand, the conjunction of the centrally explanate flagellum ^Wth obliquely impressed abdominal segments is so'strilving that one regrets the futility of trying to recall such a one to mind. The single species is shortlv diagnosed : — 10 ICHNEUMONIDAE. x/ I. Closteroceros sericeus, Htg., I.e. Black. Head, Avith the face grey-pilose, and both labrum and palpi flavous. Antennae with the second joint [scape] flavous beneath, and the eleventh to twenty-second externally white-marked. Thorax grey -pilose. Abdomen with the basal segment grey-pilose. Legs red, with the front coxae and all the trochanters flavous, hind tibiae and tarsi infuscate. Wings flavescent-hyaline, ^^ith the red stigma basally hyaline and the tegulae flavous. Length, 15 mm. ^ only. Bred on 5th July, 1837, from elder- wood. The larva had, in all probability, been parasitic upon that of some Ceramhyx [Longicorn beetle]. OPHIOGASTRA, Ashmead.— Canad. Entom. 1900, p. 368 ; Ophiodes, Htg. Ber. Naturw. Ver. Harz. 1847, col. 18 (nee Wag. 1828). ■ — This genus, lilie Glosteroeeros, has been entirely neglected since first erected. Though its author expressly says " Habitus : inter E'phialtidum, Liseonothidum [sic] Xorididr.mq'e.''^ Dalla Torre places this among his " genera sedis incertae " in 1902 ; Ashmead, in 1900, had no laiowledge of it, and did nothing but alter the preoccupied name, \vhich he misquotes as 1840. Hartig's description may be translated : Head transverse and broader than the thorax, with the mandibles apicallj' narrow and bidentate ; labium rotundate, appendi- culate and concealed ; maxillary palpi with five setaceous joints, the labial three-jointed. Antennae slender, filiform, twice or in ^ thrice the length of the thorax. Thorax elongate, narrow and sub- cylindrical with especially the metathorax elongate and subconical. Abdomen double the length (jf the tiiorax, slender and cylindrical ; of $ with the five basal segments double or more as long as liroad, and the tereVjra elongateiy exserted with small cerci ; of ^ with the second to fourth segments one-and-a-half times as long as broad ; basal segment of ^ more than thrice, and of $ [misprinted (J] more than twice as long as broad, gradually constricted towards the base, with lateral tubercles before its centre.

The species is said to have been repeatedly takeii by Herr Saxesen in the Hartz Mountains ; but Hartig Avas uncertain respecting the correct association of the above sexes. PIMPLIDES. 11 [There is not the smallest doubt in my o\ra mind that at least the FEM.\LE of this species is synonjTnous with ri/racnion (Holmgren, Sv. Ak.

Soc. 1877, p. 411. This genus is but slightly removed from true Ephialtes- species in the strong lateral sulci of the two basal segments, the more slender petiole, subglabrous thorax, basally sub- tuberculiform metapleurae, lack of metanotal carinae and also, perhaps, in its enormously elongate terebra, basally flavous abdomen and costally mfumate wings. This is one of the unlucky thirteen " Genera Ichneumoninarum sedis incertae" of Dalla Torre's Catalogus, among which 1 have had the good fortune to ascertain the position of Cryptocentrum (Entom. 1910, p. 243), Microleptes (Ichn. Brit, iv, 1911, p. 22*), Tilgida (Fauna Brit. India Iclm. i, 1913, p. 317), and the present genus, of which but a single species is kno\vn. I. Dolichomitus longicauda, Smith. Proc. Zool. Soc. 1877, p. 412, pi. xliv, ngg. 2 et 2a, $. This remarkable and beautiful insect varies in length from 18-25 mm. ; the largest specimen in the British Museum is Smith's type, ^\'hose terebra is exactly 150 mm. in length, * Herr K. Pfankuch applied to the authorities of the Breslau IMuseum for permission to examine the type of Microleptes splendididcs, Gra\'., but, he writes me ou 20th March. 1912, " doch ist derselbe total defekt, so dass er mu' niclit raehr mitgeschickt werden ivonnte. . . ]Mir ist sie ganz unbelcamit " (cf. also Deut. Ent. Zeit. 1012, p. 4,"i9). M. Roman of Upsala tells ine, in lit. May, 1912, that he considers it to be the same species as Miomeris glahriventris, Thoms. Opusc. Eat. xii, p. 1317. 14 ICHNEUMONIDAE. and another specimen of 21 mm. has the terebra 142 mm. in length. The type was obtained through Parzudaki in 1853, and is from Colombia, whence Lord Avebury presented another taken by Dr. J. D. Mallerins in 1902 ; in 1889 Senor Vergara presented five from Bogota, and another came in from Mr. Harold Hodge in 1909, from the State of Darien, also in Colombia. I have seen a specimen in the Warrington Museum from the same locality ; and M. Jules de Gaulle has kmdly allowed me to examine others in his collection from Sante Fe de Bogota and Ibague in Colombia ; neither the male nor the species' economy seem yet to be known, though in all probability it preys, like Ephialtes, upon Longicorn Coleoptera deep buried in the wood of trees and only to be reached by a specialised ovipositing apparatus. The remarkable resemblance should here be noted between the above Ichneumonid and the Braconid, " Bracon " doUchurus, Cam. (Manchester Memoirs [4] i, 1888, p. 176, ?), also from Bogota ; the body of the type, in the British Museum, is 11 J mm. in length, and the terebra measures exactly 150 mm., and even then a close examination proves it to have been broken oif ! EPHIALTES, Schrank. Schr. Fauna Boica ir, 1802, p. 316 («ec Keys, Bias. Aves, 1840). A genus of strongly elongate, subparallel-sided insects, usually black, sometimes dark red, and very rarelj^ flavidous with black markings ; usually with terebra as long as, or longer than, the whole body ; and invariably with the third abdominal segment longer than broad, by which character alone the shorter species are to be distinguished from Exeristes, as I have mdicated under the latter genus. The species are numerous, as is usually the case of an old genus, and prey upon all kinds of lignivorous larvae, both Coleopterous and Lepidopterous. Four Lidian species described under this genus by Cameron {E. latiannulatus, Tijds. v. Ent. 1907, p. 96, ? ; E. longiventris, Zeits. Hym.-Dipt. 1908, p. 37, ? ; and the possibly synonymous E. nigritarsis and E. nigro- omiculaius, Manch. Mem. 1899, pp. 148, 150, (J?) I have not seen, and have simply reproduced the original descriptions in my Fauna of India ; the elongate Pimpla gayi, of which Spinola has given so lively a figure (Gay, Hist. fis. Chile Zool. \^, 1851," p. 502, pi. iv, fig. 2) is referable to the Xoridides, as is proved by several examples I have examined. PTMPLIDES. 15 TABLE OF SPECTER. (14) I.

This was in a swamp at Dachauer Moos, near Munich ; and in the British Museum is a beautiful series of eighteen females, all labelled " Moos " by Bucheker, who captured them on the 8th, 18th, and 21st August, and on 11th September ; one is labelled " arundinis, Buch.," from whom Kriechbaumer probably adopted his specific name, since these examples were received in 1881. 4.

" Ichneumon niger, abdomine ferrugineo : primo segmento toto, reliquis punctis duobus nigris. Habitat in America, Mus. Banks." Fabricius' diagnosis does not fit this species exactly, for the abdomen is mainly clear ferrugineous, with only its base — unliJve Cresson's Cuban E. rufcscens (Philad. Soc. 1865, p. 38) — more or less nigrescent ; however, the type, which is still extant in the Banks Cabinet in the British Museum, leaves no doubt upon its identity, as I pointed out (Entom. 1909, p. 135). It is strange that Cresson nowhere mentions this species, though — at Proc. Acad. Philad. 1873, p. 394 — he brings forward a similar female from Orizaba in Mexico as E. airice.ps ; but the latter has most of the thorax also ferrugineous, and the second to fifth abdominal segments apically black on either side. E. irritator is recorded from 18 ICHNEUMONIDAE. Carolina and other North America,n localities ; in the British Museum are a couple of females from Michigan (Rev. T. A. Marshall) and New York. Walsh (Proc. Acad. St. Louis 1873, pp. 110-112) remarks that some females are double the size of others ; he did not know the male which is still, I believe, undescribed. I have examined the type of E. nigricans. Cam. (Biol. Centr.-Amer. 1886, p. 263, pi. xi, fig. 5), taken by Champion at San Geronimo in Guatemala, and find it to be nothmg but a form of the present species with the abdommal nigrescence more extensive and the hind femora concolorous ; in a series of a dozen examples of both sexes, subsequently taken by H. H. Smith at Omilteme, Xucumantlan and Amula in Guerrero, at 6-8,000 ft. in July and September, I find the huid femora are partly, entirely, or not at all, black, the abdominal nigrescence variable in extent and the anterior legs are pale stramineous with only their coxae black. 6. Ephialtes bicolor, Brulle. .Nat. Hist. Ins. Hym. iv, 1846, p. 82, ?. A dull feiTugineous species with the mesopleurae san- guineous, orbits and part of legs stramineous, and the front wings costally flavescent. Head subcubical and not constricted behind the internally emarginate eyes, black with all the orbits except at vertex distinctly stramineous and a band across the vertex, behind the ocelli, concolorous ; frons subglabrous and not carinate ; face infuscate-pilose and sparsely punctate, with its centre elevated and apex discreted from the impressed clypeus ; mandibular teeth obtuse and subequal in length ; palpi not pale. Antennae black, with scape not pale beneath. Thorax ferrugineous, nitidulous and but finely punctate ; prothorax and sutures darker, mesopleurae and scutellum paler, red ; notauli remarkably deeply impressed, with the central lobe apically produced and longitudinally sulcate throughout ; meta- thorax smooth, but somewhat distinctly and divergently bicarinate from centre of its base ; petiolar area laterally elevated apically on either side ; lateral carinae entire, spir- acles elongate-oval. Abdomen dull ferrugineous and closely punctate with apices of three first segments indefinitely nigrescent and the third subapically flavidous ; tubercles of third to fifth segments distinct, though not very strong ; basal segment nearly impunctate, both discally and laterally sulcate throughout, slender and nearly double as long as broad ; the following but slightly longer than broad, the PIMPLTDES. 19 second apically explanate A\ith strong and linear basal gastrocoeli ; terebra as long as whole body, black with spicula rufescent. Legs indistinctly flavidous, with the femora and tibiae more or less red -lined beneath ; all the coxae ferrugineous. Wings not broad, subhyaline with the costal margin of front ones strongly flavescent ; radix and tegulae dark ferrugineous, stigma bright fulvous ; areolet triangular, broader than high, sabsessile with the inner nervure continuous with the outer radial abscissa, emitting the evenly curved recurrent nervure from its apical fourth ; lower wings with recurrent but half the length of the internal radial abscissa ; nervellus intercepted at its upper fourth. Length, 18 mm. ? only. BruUe says the wings are hyaline, the thorax discally smooth and the legs more profusely ornamented ; but the salient features of his species, which has not been referred to in literature since first published, agree to a satisfac- tory extent. His type came from Minas Geraes (Aug. Saint-Hilaire) ; and the specimen above more adequately described was obtained by the British Museum in 1888, through Herr Fruhstorfer, wiio captured it at Theresopolis, near Desterro, in Brazil, on 25th October, 1887. 7. Ephialtes annulicornis, Cam. Biol. Centr.-Amer. 1886, p. 202, $. Cameron only knew four females of this species, though he indicates no sex ; these are from San Geronimo, at 2-3,000 feet at San Isidro in Guatemala, and at 2-5,000 feet on the Volcan de Chiriqui in Panama (Champion) ; M. Salle found a large example of the same sex at Oajaca in Mexico in 1858 ; and Herbert Smith subsequently discovered two or three at Teapa in Tabasco during February and March. The pale-banded antennae are unique in the present genus, and the position of the band, at the basal third of the flagellum, very unusual among Ichneumonidae. 8. Ephialtes manifestator, Linn.

Not uncommon in northern Europe, and well represented with us ; in Britain it appears commonest in the Scottish pine woods ; Smtzerland ; Germany ; Sundalen in Norway 02 20 ICHNEUMONIDAE. in July, 1901 (W. F. Kirby). A female, captured by H. Edwards at the summit (14,898 feet) of the Sierra Nevada in California, and presented to the British Museum in 1884, differs in no way from European examples ; it agrees exactly with Cresson's account of his E. occidentalis, though the hind legs and ovipositor are no longer, the abdomen is no narrower, and its segments are no longer than in E. manifestator. I would suggest that the abdomen of his single Coloradan female was artificially compressed. 9. Ephialtes iridipennis, Mori. Fauna Brit.

Frederick Smith described the male, female, and a female variety of this species ; only the typical female, from Hiogo in Japan, is indicated in the British Museum, though a broken male from the same source labelled " var. investigator " (a MS. name) seems doubtless the male referred to. The species is extremely like a true Pimpla, but the tarsal claws are strongly lobate, and the flagellum is not filiform ; the flavous-and-black posterior coxae, pale scutellum and stoutly bicarmate metathorax are noteworthy ; the hind knees are black as in Pimpla indra, but the centre of their tibiae, the anterior legs, tegulae and sides of the face are flavous, which instantly distinguishes it from P. luctuosa.

Doubtless Mr. Ti^^on has had but small experience in Parasitica, or he would know this is ssaionymous with the commonest of all Australian Ichneumonids, Lissopimpla semipwictata, Kirby (cf. Revis. Tclin. ii, p. 34). His account of the economy is, nevertheless, extremely interesting. He says it destroyed a very large percentage of the grass-feeding larvae of Spodoptera manritia in the Tingalpa district during AprU, 1895, and that the imagines were so abimdant in pastures at Rockville, Mombra, diu-ing the catei-pillar plague of 1896 as to attract the attention even of the graziers. It emerges from subterranean Lepidopterous pupae. PIMPLIDES. 47 23. Theronia melanosoma, sp. n. A very fine and dull red-testaceous species, with the mandibular apices, antennae, hind legs and the nitidulous abdomen black, Avith wings evenly and somewhat strongly infumate, though not nigrescent, tlu'oughout ; the flagellar joints are much more apically setiferous than is usual in the present genus, the vertex broader behind the eyes, the metanotal lateral carinae are unusually prominent and apically foliaceous with metathoracic apex laterally sub- produced on either side, the frons is strongly impressed and stigm I uifuscate ; the ? has the terebra three-quarters of the abdominal length, the two basal segments apically flaWdous on either side, and the first is basally testaceous ; length ? 12, S 14 mm. A single pair was captured by Turner in February and March, 1902, at Kuranda near Cairns in Queensland. 24. Theronia flavistigma, sp. n. Similar to the last, but entirely nitidulous and ferrugmeous with the terebra, antennae and broad mandibular apices alone black ; occiput centrally emarginate ; areola not stronglj^ costate, parallel-sided A^dth slight lateral indication of an apical carina ; wings infumate and distinctly a little paler apically, though not basally ; their costa nigrescent to base of stigma and thence bright flavidous ; terebra only half abdominal length ; length 12 mm. ? only. The type was acquired m 1887 from C. M. Woodford, v.ho captured it in the Solomon Islands. 25. Theronia fumipennis, sp. n. Of the usual testaceous facies, but kno\\7i from all other such species by its strongly and evenly infumate, though not nigrescent, wings ; the metanotal carmae are somewhat weak, and areola entirely open apically ; terebra almost half abdommal length ; length 11-12 mm. ? only. The type was captured at To\nisville m northern Queensland by F. P. Dodd ; and three other females were presented by Turner in 1909 from Mackay. *' 26. Theronia viridicans, sp. n. (?

The typical female -v^as captured by E. T>. Atkinson in south-east Tasmania in 1877, a second taken by C. French in Victoria during September, 1901, and there is a paii*, also from Victoria (C. French), in the British Museum. 27. Theronia claripennis, sp. n. (? T. dubia, Krieg., Zeits. Hym.-Dipt. 1906, p. 320). So similar to the palaearctic T. atalantae in every way as to be distinguishable only by its ajjically incomplete metanotal areola, black antennae and tarsi ; length 9-11 mm. S ?. The type was captured near Sydney m 1856 by Cuming, a second male was secured during April, 1899, at Mackay in Queensland by Turner, and both F. du Bouiay and C. French found females in Victoria. NEOTHERONIA, Krieger. Sitzb. Naturf. Ges. Leipzig 1897-8, p. 48. This genus is exactly similar to Theronia in almost every way, excepting that, in place of having the metanotum more or less evenly areolated with even carinae, its apex is bounded throughout its breadth by a high and stout ridge, cutting the metathorax mto two very distinct parts. In his above- quoted erection of the genus, published in 1899, Professor Krieger did little more than differentiate it from its allied genera ; but in his admirable paper u.pon the subject (Zeits. Hym.-Dipt. v, 1905, pp. 286-307 and 333-338) he enumerates no less than fifty-five species, all from central and southern America, vaih. the exception of one from northern Carolina. Only four were a cribed by him to Mexico, whence came most of the material in the British Museum, and two from Cuba, a locality which is little kno^^'n to us entomological ly in England. That the first two species of Theronia, tabu- lated by me under Africa, belong to the present genus is not improbable (cf. Szepl., Kilim.-Meru Exped. 1910, p. 84). Mr. Ernest A. Elliott has been good enough to allow me to X^ublish the follo^^^ng translation he has carefully draMU up PIMFLIDES. 49 of the distinctions used by Krieger in his specific synopsis referred to above ; a study of this particular group affords an excellent example of how numerous Ichneumonidae may be in a little-worked area, and of how appalling the number of species is lilcely to prove ^vhen a comparatively complete knowledge of them has eventually been attained.

It occurs sparinglj^ in north and central Europe, but seems little understood. I have hitherto been unable to confirm it as British (cf. Ichn. Brit, in, p. 92), though the following note, found by me since 1908, mil add something to that probability : " New British Ichneumon. — Having bred some Ichneumons from the pupae of Odontia dentalis, and not knov/ing them, I sent a pair to Mr. Desvignes, and received from him the follo"\^ing reply : ' The Ichneumons you have sent me, reared from Dentalis, appear to be Piyrvpla mandi- bularis, Grav.

The type is in the British Collection in the British Museum, and the species has hitherto been recognised only from England (Devon and Hampshire), but Rathe sent a male and two females to the British Museum in 1859 from Germany. On 12th February, 1909, the late Mr. Bignell wrote to me : "I would like to mention that it is the young spiders that are consumed, and not the eggs. I believe the statements " bred from spiders' eggs " are errors of judgment and have originated by seeing the egg-shells in the egg-bag, after the escape of the parasitic -fly. In fact, I doubt if the young parasite has sufficient power to penetrate the egg-shell. All nests or egg-bags I have brought home for observation confirmed this ; I should not like to state how many nests of different species I have brought home for that purpose — all with the same result." 5.

I do not know this Tenerife species, but the description leaves little doubt that it should be ascribed to the present genus. 7. Itoplectis platana, sp. n. A black species, A\-ith metathorax red and all the segments white-margined. Head posteriorly narrow, with the Irons and vertex subglabrous ; face strongly punctate and elongately pilose, clypeus depressed and palpi stramineous. Antennae stout and not short, distmctly attenuate basally and apically obtuse ; postannellus nifescent. Mesonotum subdeplanate, with sparse and elongate recumbent pilosity ; notauli \\'antmg ; mesopleurae shming with shorter hau"s and then- base red-dotted below ; metathorax red, evenly and superficially punctate, with elongate pale pilosit}'^ ; areae entirely wanting, though the basal is represented by a glabrous space ; spiracles not circular. Scutellum a^pically, postscutellum and the freni of both flavous. Abdomen black, strongly and evenly punctate with apices of all the segments, more broadly laterally, strammeous : remainder of basal segment red, its carinae strong and far apart, extend- ing to and coalescing a,t the apex, with basal fovea large ; tubercles of central segments distinct and the gastrocoeli of the second both stramineous and very deep ; s valvulae strongly exserted, ? terebra pilose and hardly half length of abdomen. Legs neither slender nor elongate, flavidous-white • hind coxae except apically, and all the femora except apically' red ; apical half of posterior tibiae and apices of then- tarsal joints, with both extremities of hind femora and base of their tibiae, black. Win.gs hyaline and not narrow : stigma castaneous, areolet sessile and emitting recurrent ner\n.ire from beyond its centre ; nervellus mtercepted far above its centre. Length 9-12 mm. S ?• It appears allied to Pimpla tricolor, Brulle, 1846 {ncc Spinola, 1840). Four males and a female were captured at La Plata City in Argentina between 28th and 30th May, 1896, and presented to the British Museum by Colonel Yerbury. 8. Itoplectis sponsa, Hal. Pimphisponsa, Hal., Trans. Linn. Soc. xvii, 183(), p. ,318, 2. I have already noticed (Entom. 1911, p. 213) that Haliday's unique and remarkable female, which is extant in the British 80 ICHNEUMONIDAE. Museum and bears his label, is referable to the present genus, since the antennae are distinctly attenuate basaliy and subclavate towards their apices, with the mesonotum recumbently pilose. The entirely black head, thorax, scutellum, legs and a.nus with deep red mesonotum, abdomen and hind femora except apically, render it very distinct ; while the evenly nigrescent wings with very faint cyaneous reflection, their centrally intercepted and subopposite nervellus, sparsely punctate and centrally sulcate metanotum, strongly tuberculate abdomen v/ith its remarkable ephippi- form petiole, and the internally stramineous front femora and tibiae characterise it. The terebra is, as Haliday says, shorter than half the abdomen, with black and pilose valvulae. Length 9 mm. $ only. The type is from Valparaiso, and is obviously closely allied to Pimyla hraconoides, Gay (Hist. fis. Chile, Zool. vi, 1851, p. 501, S ?), in having its wings infumate, mesonotum and abdomen deep red, but P. hraconoides is less immaculate black and has the terebra much longer. I have seen two males in the British Museum, captured at Atoyac in Vera Cruz during April by Herbert Smith, which may represent the other sex of Haliday's species, though the hind tibiae are stouter and centrally dull white, the mesonotum is black, the head cubical, the nervellus intercepted at its lower third and the basal segment is strongly bicarinate to its apex and not elevated ; the length is only 6 mm., and, unfortunately, no female was taken along Avith them.

The type is m coll. Fred. Smith (mus. Janson) and is labelled " Brasilia. Capta D. Swainson." Australasian, Malayan, and Asiatic Species. 3. Hemipimpla clotho, sp. n. A testaceous and subglabrous species Avith the antennae, hind legs and the tuberculate, punctate abdomen black ; \\-ings entkely infumate tliroughout with stigma and a very indefinite area below it in the cubital cell nearly clear ^hite ; head and mesonotal vittae often flavidous ; areolet not large, externally continuous with second recurrent nervure ; length c? ?, 9-15 mm. On more meagre material, I should not dare to consider these Australian specimens distmct from those of the Malay Archipelago, m spite of the more convex and sparsely punctate central area of the first segment ; but throughout the score of both sexes which I have seen in the British Museum, where is the type, the abdomen and hind 94 ICHNEUMONIDAE. legs are entirely dead black and the A\ings are not basally paler, moreover the cubital cell is much less definitely pellucid above, the abdomen is not laterally white-marked, and its tubercles are a little more distinct. This species appears to be one of the commonest of Pimplids about Mackay and Cairns in Queensland, and I suspect a female labelled " New Guinea " of also being Australian. Compare Camptotypus sellatui and C. hicolor, Knech. (Ent. Naclir. 1889, p. 311), which are certainly not synon3anous and, in my opinion, not congeneric. 15. Hemipimpla atropos, sp. n. Extremely closely allied to H. hraconoides, Smith, but instantly known by the entkely glabrous and very highly nitidulous (or in S rarely roughly punctate) disc and sides of the elevated central area of the basal segment, by the larger and brilliant stramineous stigma, surmounting a very definite and entirely hyaline area in the cubital cell of the otherv.ise, except basally, evenly infumate wings ; the head is larger, the thorax stouter and much more convex, and the abdomen is less convex with its basal segment much flatter ; length c? ?, 12-15 mm. Described from four males and a female from Mackay in Queensland. 25. Hemipimpla lachesis, sp. n. Possibly no more than a form of the last species, but sufficiently distinct in its jet-black vertex, laterally prominent though not spinate metathorax, centrally punctate and in S excavate centre of basal segment, the distmctly though indefinitely red anus, in the clear fulvescent-hyaline basal half of all the wings, with those of the ? sanguineous-red above the hyaline cubital area ; length, cJ 10 mm., ? 14 mm. A single pair in the British Museum ; the male \\'as taken in February, 1900, at Mackay in Queensland, and the female in Victoria. There is also an unlocalised female in Frederick Smith's collection (mus. Janson). 14. Hemipimpla braconoides, Smith. Pimpla braconoides, Smith, Joum. Liim. Soc.

Both sexes — not ? only, as given by Dalla Torre — are described from " Key Island " by Frederick Smith. In the PIMPLIDES. 95 British Museum is the original cJ from Aru, two co-typical $ $ from New Guinea and Ai'u, with another captured by Edward Daniel in the Celebes in 1858. " The fourth and follomng segments of the abdomen " are described as black in $, and the (S " with only the basal segment yellow " ; the co-typical females have respectively the two basal segments except the apical elevated margin of the second throughout, and the first with only basal lateral angles of the second segment, testaceous ; while in the Celebes example the second segment is apically extremely obsoletely uifuscate. Smith adds : " This species might at first sight be mistaken for a species of the genus Bracon," and so appropriate is the remark that the late W. F. I^by actually described the female, taken by the Challenger Expedition in Ki Dulan on 25th September, 1874, under that genus ; his type, also in the British Museum, differs very slightly in having the third segment, except its apical angles, also testaceous, the wings basally more fulvescent and the stigma conspicuously stramineous in place of conspicuously whitish, probably owing to discoloration. Both this and the above closely allied Australian species have the apices of the anal, and apical angles of the central, segments narrowly \\'hitisli. 22. Hemipimpla infirma, Smith. Pimplainfirma, Smith, Joiuii. Liiiu. Soc. Zool. iv, 18C0, Siippl., p. G3, $ ; Erythropimpla testacea, Cam., Tijds. v. Ent. 1907, p. 98, $. A co-type from Amboyna, placed by Smith m the British Museum proves this species to be identical with Cameron's Erythropimpla testacea, ?, both sexes of which are treated by me under the present genus in Fauna of British India, Ichneumons 1913, p. 188 ; it is knovrn to extend through Burma and Assam to Sikkim ; Smith records it from Makassar ; and in the British Museum is a ? presented by the Admiralty and captured during the voyage of H.M.S. " Penguin " between 1.3th and 17t]i November, 1891, at Amboyna. It is a true member of the present genus, and has no association with Xanthopimpla, as suggested by Dr. Krieger (Sitzb. Nat. Ges. Leipzig 1899, p. 65). The entirely testaceous body and legs, with broadly infumate alar apices render it a conspicuous species. The Berlin Museum possesses a score from Sikkim and one from Sumatra (Bingham Coll.). 96 ICHNEUMONIDAE. S3. Hemipimpla obnoxia, Smith. Pimpla ohnoxia. Smith, Journ. Linn. Soc. Zool. viit, 186i, p. 64, ^. This species hp^s not been mentioned since first superficially described by Smith from Morty Island. A co-type from his collection was acquired by the British Museum in May, 1879, and differs from H. inflrma solely in having the wmgs strongly infumate throughout Anth only their base, and a shade below the stigma in the cubital cell, flavescent. It is the only example I have seen, and very probably constitutes no more than a form of the last species. 23. Hemipimpla flaviceps, Smith. Pimpla flaviceps, Smith, Joiuii. Linn. Soc. Zool. iv, 18G0, Suppl., p. 139, ? (nee Brulle). Although this species and H. infirma are described in the same year and Supplement, the present occurs in a different paper and, if found synonymous, must fall to the latter name, from ^^'■hich it differs in nothing but its more coarsely, though still sparsely, punctate metathorax, the glabrous and not rugose lateral areae of the basal segment and in having the wings infumate from the basal nervure of the upper and from base of the radius in the lower wings (and not, as in H. infirma, only from the apex of its testaceous stigma) to apices of the wings. It is an mtermediate form, connecting H. m/irnia and H. obnoxia ; originally recorded from Batchian, but a co-type ex coll. Smith in the British Museum is from Morty, 20. Hemipimpla olynthia, Cam. Pimpla olynthia. Cam., Manch. Mem. 1899, p. 156, $ ; cf. Tijds. v. Ent. 1907, p. 99. In my Fauna of British India, Ichneumons i, 1913, p. 189, I ventured to synonymise this species with Hemipimpla caffra, Sauss., but the former's description, which directly applies to the oriental and not the African species, is there correctly reproduced. This agrees well enough with Saussure's account of his species, but a comparison of the types of both in the British Museum shows Cameron's species to be a much larger and stouter insect with the vertex broader, the eyes internally much less emarginate, the notauli obsolete, metanotum laterally less strongly punctate, the basal segment PIMPLIDES. 97 centrally bicarinate and elevated to a remarkable degree ; the abdomen is centrally broader with the segments discally much smoother and less uniformly punctate ; the teiebra is exactly, or very nearly, as long as the body ; the legs are stouter, A^-ith hind tarsi red ; the lower wing has the apical infumescence hai'dly extending to the evenly rounded hind margin ; but the neuration is identical, excepting that the areolet is narrower, less petiolate and emits the recurrent nervure nearer its apex. The half-dozen examples in the British Museum are from Sikkim and Burma ; it is also known from Assam. A score of Bingham's Sikkim specimena are in the Berlin Museum. 4. Hemipimpla rugosa, DeG.

Zool. Ajinalen 1911, p. 28, ?. I have fully discussed (Fauna Brit. Ind. Iclm. i, 1913, p. 190) the propriety of adopting DeGeer's ancient name for this species. Pimpla viridipennis, the type of which in the Oxford Museum and the original variety in the British Museum I have now seen, are its male. It is the only oriental species Avdth uniformly deep black wings, and is well repre- sented in the British Museum. It is still uncertain whether this species extends so far north as Burma ; Schulz 's females from Toli-Toli in the northern Celebes and Kudat in north Borneo are probably this species, he also records it from Manila in the Philippines. A specimen ($) in the Berlin Museum is from Tengar, Perak. 12. Hemipimpla ariana, Cam. Pimpla ariana. Cam., Manch. Mem. 1899, p. 157, ? ; cf. Tijds. V. Ent. 1907, p. 99. Very like H. rugosa but stouter, with the abdomen broader and wings, except at their apices, flavescent. It is only known from the Himalayas at Silddm and various mountains in Assam ; several examples from the former, and one from the latter, locality are in the British Museum. I have recently examined twenty-five examples in the Berlin Museum, taken by Bingham in Sikkim (Rungarum in April, 1900, etc.) and Sumatra. ICHNEIJMONIDAE. 13. Hemipimpla philippina, sp. n. Most closely allied to H. ariana, though mth the abdomen less uneven, more finely punctate, with the segmental apices less laterally prominent ; all the legs are pale fulvous, with only the hind tarsi and tibial apices infuscate. The scape, head, thorax and two basal abdominal segments are testaceous, Avith the apical margin of the last and whole remainder of the abdomen black ; terebra 14 mm. in length ; the metathorax is glabrous with only its disc punctate, all carinae wanting. It is at once known by the unique coloration of the wings, both pairs of which are bright flavous (those of H. lachesis are alone similar) nearly as far as the basal nervure of the upper, or a little beyond the nervellus in the lower, pair and thence strongly and determinately nigrescent throughout, with stigma also black and no pale area below it ; length 17 mm. ? only. The type was captured on 29th May, 1906, .at Luzon (Benquet Province of Irisan) in the Philippine Islands, and is in the British Museum. American Species. 17. Hemipimpla maxima, sp. n. CSee Plate.J A magnificent black species with the metathorax and basal two-thirds of the abdomen deep crimson, and the wings infumate Avith a paler cloud below the areolet. Head immaculate with vertex not very narrow behind the mternally slightly emarginate eyes, but abruptly declivous behind the elevated ocelli ; frons smooth and a little impressed on either side. Antennae immaculate and but slightly longer than abdomen, with flagellar joints cylindrical and apex sub- attenuate. Thorax glabrous and very strongly nitidulous, with notauli superficial ; black with whole metathorax and apical mesopleural sutures deep rich red ; metanotum hardly impressed centrally, sparsely pale-pilose, with subcircular and not very small spiracles, Scutellum glabrous and deplanate, its centre and the apex of postscutellum rufescent. Abdomen stout and rich red with the fifth and following segments, except very narrowly at their apices on either side, deep black ; first segment smooth, basally excavate, not longer than apically broad, with no carinae ; the second to PIMPLIDES. 99 sixth with a strong tubercle and apical elevation on either side ; remainder smooth ; terebra black, as long as abdomen and unusually stout, with its base beneath fifth dorsal segment ; spicula black and very strong. Legs neither elongate nor slender, black with front tibiae externally and apex of femora internally testaceous. Wmgs mfumate throughout, though with apical third of the cubital cell much paler below areolet,* which is sessile and twee as broad as high, emitting the evenly curved recurrent nervure but slightly before its apex ; nervelet extremely elongate and parallel Adth the black costa nearly to the upper basal nervure; stigma black; second recurrent of lower wing very strongly reflexed. Length 17-19 mm. ? only. The type and a co-ty|3e were captured by H. W. Bates at Para on the Amazon and were received by the British Museum in 1848 or 1849. Perhaps it is not rare there, for three other females from the " Amazon " and "Para" are in Frederick Smith's collection (mus. Janson), with one from " Chili " ; all these have subunicolorous infumate Avings. 1 8. Hemipimpla recta, sp. n. Extremely like the last species, though smaller, ^^ith the metathorax black and the v.ings bifasciate. It further differs therefrom in its flavidous palpi, discally subglobose head with very strongly emarginate occiput, entu-ely black thorax and scutellum, the acutely impressed disc of the second and third segments, distinctly shorter terebra of normal thickness and rufescent spicula, the laterally entkely testaceous front legs and basally subhyaline wings as far as the basal nervure ; their centre from apex of stigma including areolet to anal nervure is also hyalme ; lack of nervelet, the slight second recurrent of lower wmgs and lower interception of the nervellus ; but especially is it distinct in having the basal abdominal segment abrutly elevated and strongly carinate on either side. Length 12 mm. ? only. The smgle Venezuelan female was acquu'ed by the British Museum from Dyson early in 1847. * In the co-type is a most curious neurational aberration, which I have seen nowhere else. The dexter areolet is succeeded at the basal top of the outer cubital coll by a very small secondary and subcircular areolet, formed by duplication of its outer nervure ; in this specimen only, the second recurrent emits an external nervelet. h2 100 ICHNEUMONIDAE. 19.

Cent.-Amer. 1886, p. 272, $. Cameron elevated this species to generic rank on account of a hind femoral prominence and some slight modifications in which latter it differed from Pimpla, but entirely agrees with Hemipimpla, where it may nowadays be fairly included. The pale legs and hind femoral excrescence render it con- spicuous among the occidental species. Its distribution is South American, and it does not appear to extend to the Province of Sonora, nor did Herbert Smith find it about Guerrero, etc., among many thousands of other Parasitica. Five examples in British Museum, all — except in one doubtful case — females ; Cache in Costa Rica (Smith's type) ; Valla- dolid in Yucatan (Gaumer) ; Honduras in 1845 (Dyson) ; British Guiana in 1908 (J. Rod way), and Brazil about 1838 (Mornay) ; Cresson's type was from Cordova, Mexico. African Species. 21. Hemipimpla caffra, Sauss. Distant's Naturalist in the Transvaal 1892, p. 227, ?. Saussure's short description from a single ? from Pretoria agrees well v.ith H. olynthia, though an exammation of three topotypes in Distant's collection, of which one is a c?, show the marked distinctions set forth above under the latter species. Here the hmd A\dng is conspicuously emarginate with its border infumate throughout its apical tAvo-thirds ; and the terebra is hardly longer than half abdomen. It is the only African species with entirely testaceous body and the flavescent Adngs infumate only at their extreme apices. 8. Hemipimpla calliptera, Sauss, Distant's Naturalist in the Transvaal, p. 228, $ ; Pimpla limhata, Tosq., Mem. Soc. Ent. Belg. 1896, p. 295, ^ 2. Black with the head and thorax partly ochraceous ; terebra half length of abdomen ; wings basally flavescent and apically black or black-marked; length 12-15 mm. There can, I tlimk, be no doubt that Saussure's species, half-a-dozen topotypes of which from Distant's collection from the neighbourhood PIMPLIDES. 101 of Pretoria are now in the British iVIuseum, is no more than a dark variety of P. limbata, Tosq., of which the typical Cape Colony form with three subapical alar spots is recorded from Jannerill by Cameron (Trans. S. African Phil. Soc. 1905, p. 195) and represented in the British Museum from Natal, with two of the subapicallj^ banded form mentioned by him (var. semilimbata, nov.) from the same locality ; the type form with the whole alar apex nigrescent from the stigmal apex is probably not rare since Captain Munn presented it from Durban in Natal in 1891 and Neave sent three more from Masongaleni at an altitude of 3,000 feet in British East Africa, where he found them at the end of March, 1911. I have not seen the male. 6. Hemipimpla melanoptera, sp. n. Extremely like //. calUptera in structure and terebral length, but with the antennae filiform and much more slender, the wings entirely and uniformly nigrescent, the abdomen more parallel-sided and with a cyaneous reflection, the metathorax both shinmg and strongly punctate ; the head, except vertex and occiput, and both prothorax and front legs are ochraceous ; length 12-14 mm. 3 ? Both sexes (of which the male differs only in its ochraceous intermediate legs and flavous anterior coxae and trochanters) were discovered by S. A. Neave in 1911-12 in the Uganda Protectorate, on the north-west at 3,800-3,900 feet, and on the west at 3,700 feet about Buddu, shores of the Victoria Nyanza ; at Northern Buddu at 3,800 feet in September ; as aacII as between Mitiana and Entebbe at 3,800 feet in earlj^ January. 7. Hemipimpla tlavicaput, sp. n. A large black species with uniformly nigrescent \Aings and only the head, front legs, j)rothorax, mesopleurae and meso- sternum brilliant flavous ; it is similar to the last species, Avith the abdomen equally subcyaneous and parallel-sided ; but the terebral length will render it abundantly distinct, both from that and the smaller, though similarly coloured, Pimpla cognata, Tosq. (Mem. Soc. Ent. Belg. 1896, p. 299), since in both it is much shorter than the abdomen, while here it extends to exactly the same length ; the head is strongly transverse and verticallv narroA\-, the cheeks subobsolete, the 102 ICHNEFMONIDAE. scape pale beneath, the hind tibiae are basally arcuate and the abdominal tubercles weak ; length 18-19 mm. ? only. The female type, acquired from Frederick Smith's collec- tion by the British Museum in 1879, is labelled "West Africa," and if that be correct its range is wide, for the only other example I have seen was captured by Neave in the middle of September, 1911, at 3,700 feet about Buddu on the west shore of the Victoria Nyanza in Uganda. 5. Hemipimpla rubrithora.x, sp. n. An elongate black species, Avith concolorous Agings ; head except vertex, the entire thorax, scutelhim, anterior legs and hind coxae rosy. Of the size and outline of H. flavicaput, but quite distinct in its coloration, the more slender antennae, posteriorly mvich broader head, subbuccate cheeks, dead black scape, impunctate metathorax, more closely and much less coarsely punctate abdomen and sculptured basal segment, and in the very strongly elongate terebra. Length 17 mm., ? only. The type was captured by Neave in forest at 4,000 feet on 28th July, 1911, between Jinja and Busia, near East Busoga, in the Uganda Protectorate, and is in the British Museum. 9. Hemipimpla pseudoptera, sp. n. A large and stout species, immaculate black and nitidulous, with the hind tarsi red and terebra exactly as long as the body ; wings deep flavescent to centre of stigma of front ones and to slightly beyond second recurrent nervure in hind ones, and thence truncately black %\ith an irregular central spot in the anterior. I hesitate to place this species in the present genus on account of its very stout head with buccate cheeks and temples, strongly excavate scrobes, large metathoracic spkacles and the structure of the hind tarsi, w^hich are distmctly weak with the onyches (unlike the inter- mediate which are stout, curved and basally lobed) short and nearly straight, hardly extending beyond the stout pulvilli. It is very like the semilimhata form of H. calliptera, though stouter, more shining, with longer terebra. Length fully 15 mm. $ only. The type in the British Museum is from 4.800 feet in the Mpanga Forest, Toro, November, 1911 (S. A. Neave). PIIMPLIDES. 103 10. Hemipimpla verticalis, sp. n. Black, AAith the A^iiigs, except before apices of the anterior, concolorous. Head except vertically, prothorax and front legs, bright ochraceous. Unlike any of the foregoing African species in haxdng the A^'ings nigrescent throughout ^ith only a large subapical spot in the anterior, extending from centre of areolet nearly to the margin and from the anal nervure to the costal nervure, silicious-hyaline. Both cheeks and temples are very strongly buccate ; vertex and frons, but neither occiput nor scrobes, are black, as also are the apices of the equally bidentate mandibles ; metanotum impunctate and strongly glittering, scutellum and metathorax also glittering, but with a few scattered punctures ; areolet distinctly sessile, nervellus intercepted slightly above its centre ; all the tarsal claws curved and basally lobate ; terebra 13 mm. in length, body 15 mm. ? only. A single female was taken by Neave, between Mitiana and Entebbe in Uganda, at 3,800 feet, in the middle of January, 1911, and is in the British Museum. II. Hemipimpla verticella, sp. n. Extremely like the last species in the coloration both of body and mngs, but with the terebra not longer than the abdomen and both meso-pleurae, -sternum and the inter- mediate legs differently coloured ; the tarsal claws are small and strongly reflexed, the abdomen ls more coarsely and evenly punctate A\-ith its segmental apices less glabrous and lateral tubercles obsolete ; the areolet is distmctty a little petiolate and the nervellus intercepted far below its centre ; length 12-13 mm. $ only. This species is only Icnown from the Buamba Forest in the Semlilvi Valley of Uganda, vvhere Neave found it at an altitude of about 2,600 feet at the beginning of November, 1911. 26. Hemipimpla vipioides, Brulle. and var. imperfecta nov. and immaculata nov. Pimpla vipioides, Brulle, Hist. Nat. Ins. Hym. 1846, p. 96, $ ; Cosmio- pimpla jerrnginea. Cam., Trans. S. African Phil. Soc. 1905, p. 198, 5; Ann. S. African Mus. 1906, p. 116, ^ ?; Erythropimpla aethiopica, Schulz, SpoliaHym. 1906, p. 100 ; cf. Zool. Annalen, 1911, p. 31. This K^pecies has the head, thorax and abdomen immaculate fulvous ; it was originally recorded from Senegal and South 104 ICHNEUMONIDAE. Africa. The typical form has three distinct fasciae in the front and two in the hind wings, the mesonotal notauli deeply impressed and the hind legs only black " a partir du milieu des jambes " ; with the terebra 8, and body 15 mm. in length. This exactly fits half-a-dozen females m the British Museum from Obuasi in Ashanti (Dr. W. M. Graham 1908), Eriam in southern Nigeria on 21st May, 1910 (J. J. Simpson), on bank of the Mle near Kakindu at 3,400 feet, and in forest between Jinja and Busia at 4,000 feet, both in August, 1911 (S. A. Neave), and Salisbury in Mashonaland in January, 1900 (Marshall). Schulz's single female was from Usambara in German East Africa ; Cameron's typical female of 12 mm., with terebra of 8 mm., and the alar fasciae entire is from Brak Kloof in Cape Colony, and later he records it from Rondeburg in September. Holmgren has described the male of this species (Eugenies Resa Ins. 1868, p. 404) from the Cape of Good Hope, as similarly coloured to the female, but with the head and anterior legs flavescent-testaceous. Cameron adds that the wings also are paler — and thus is a northern Nigerian male taken at Lateri on 2nd December, 1910 (J. J. Simpson). Three other females (var. imperfecta, nov.) I cannot regard as distinct, since they differ solely in havuig the hind legs, except coxae and tibial base, black, together v.ith both the discal fasciae of the front \\ings more or less broadly inter- rupted. Szepligeti's Erythwpinipla trifasciafa (Sjostedt's Kilimanjaro-Meru Exx)ed. 1910, p. 79) seems, as Schulz remarks in 1911, a similar form -with the hind wings " (die ausserste Basis der Schienen ausgeuommen) und em Fleckchen an der Unterseite der Mittelhuften schwarz." The var. im'perfecta is from the Yala River on the south edge of the Kakumga Forest at 5,000 feet m February, 1911 ; on the northern slope of Mount Kenya on the Embu-Meru road at 5,000 feet in February, 1911, in British East Africa ; and at 6,000 to 8,500 feet to the north of Mount Ruwenzori at the beginning of November, 1911, in Uganda (Neave). Another pair (var. imviaculata, nov.) differ from the type form in their entirely fulvous hind legs, which bear no black markings whatever, in the rather shorter ? terebra which is only 7, to the total body length of 13 mm., and m the sparse nigrescent markings of the S wings, where the basal fascia is reduced to a prestigmal dot, the second to slight clouds below the stigma and before areolet and m the centre of the cubital cell, while the apical margm is but narrowly infumate in both pairs of wings. riMPLIDES. 105 27. Hemipimpla simillima, sp. n. I am able to distinguish this species from the last solely on its smaller size of only 11 mm., and shorter terebra of but 3 mm. ; it seems to me impossible that the ovipositor should vary to this extent, Anth no intermediate grades in the dozen females I have examined. One female and six males were captured together during November, 1910, at Zmigeru in northern Nigeria by J. W. Scott-Macfie. 28. Hemipimpla pulchripennis, Sauss. Giandidier's Hist. Phys. Madagascar 1892, pi. xiii, figg. 4, 4a, 4b, ? Madagascar. 29. Hemipimpla pulchra, sp. n, A fulvous species Avith ^^ing- markings like those of H. vipioides, of ^Aliich it appears a variety till the much more strongly elevated segmental apices, more acute abdominal tubercles and shorter terebra which is shorter than the abdomen, be noted. In coloration it is very distinct, with the head except vertically, prothorax, mesosternum, and anterior legs except base of the intermediate, flavidous ; the vertex, remainder of thorax Antli scutellum and whole remahider of the legs, are black ; length 10 mm., terebra, 4 mm. ? onlj^ Northern slopes of Mount Kenya, on the Embu-Meru road at 4,500-5,000 feet m the middle of Feb- ruary, 1910 (S. A. Neave, type). I should suspect this of being Szepligeti's E. trifasciata, but he does not tell us the thorax is black-marked. 16. Hemipimpla divisa, Tosq. Pimpla divisa, Tosq., Mem. Soc. Ent. Belg. 189G, p. 304, ?. It has hitherto only been knoAMi from the Cape of Good Hope, from Tosquinet's type in the Berlin Museum.

Hemipimpla divisella, sp. n. Extremely like H. divisa, and perhaps no more than a colour variety of it, differing mainly in its unicoiorous pubescent abdomen and much smaller hyaline area below the stigma, and in its northern distribution. One male and two females were taken by Scott-Macfie at Zungeru in northern Nigeria in November, 1910 ; and by Neave at 3,700 feet on the Mbale-Kumi road, south of L. Salisbury in Uganda, in the middle of August, 1911. 30. Hemipimpla bifasciata, sp. n. A fulvous species, with the hind tarsi and tibiae black, very closely allied to H. vipioides in every way but \\\t\\ the alar apices dark and, in front wings, only a single chscal transfascia from the a.pical two-thirds of the stigma to the sinus and, at the latter, confluent with the outer margmal band. It is certainly not a variety of that species, for the head is much broader behind the eyes with vertex stout and face transverse, the notauli are wanting and the metathorax subimpunctate, the areolet is not at all petiolate and the nervellus is intercepted distinctly above its centre, the basal segment is much shorter, more convex and distinctly sulcate centrally, the following are more closely punctate and convex with stronger tubercles though, as in that species, the second and following segments are often black-dotted apically on either side ; length 14 mm., terebra 8 mm. It is the only African species A\ith bifasciated wings, and occurs principally in the south : at Durban m 1855 (Guenzius, type), Barberton in Transvaal (Distant), and Delagoa Bay (Mrs. Monteiro, 1886) ; though a small male (8 mm.) was secured by Neave in October, 1911, to the south of Lake George in Uganda, 3,200-3,400 feet, and I possess a female of 20 mm. from West Africa, 31. Hemipimpla umbrata, sp. n. Black, with the abdomen dark red, head and front legs and prothorax ochraceous, and the wings strongly clouded. Head vertically narrow and strongly transverse, entirely flavidous- ochraceous with mandibular apices and the internally distinctly emarginate eyes alone black. Antennae filiform, PIMPLIDES. 107 setiferous and longer than half body, black, with scape pale beneath. Thorax glabrous, nitidulous, impunctate and black, with prothorax ochraceous, notauli deeply impressed and the metanotum distinctly punctate only at the base on either side, centrally sulcate at its apex ; spiracles small and circular. Abdomen rich deep red, strongly punctate and subparallel-sided ; first segment with base and sides of second especially roughlj' punctate, the former very slightly longer than apical ly broad with distinct basal though no discal carinae ; sixth and following segments not tubcrculate ; terebra black and nearly half length of abdomen. Legs dead-black, with the intermediate badious and the front ones pale ochraceous. Wings nigrescent with the front ones, from base of tlie fulvous stigma to centre of bi-achial cell and thence nearly to apical margin, flavidous-hyaline, slightly clouded at the stigma and centre of cubital cell ; hind wings nigrescent with a single pale transfascia at the second recurrent nervure. Length 15 mm. Apparently allied to H. pulchra, which has the wings basally pale. Three females with varying density of alar infumescence were taken by C. C. Gowde}^ and S. A. Neave in Uganda in the Daro Forest of Toro at 4,000-4,500 feet in October, 1911 ; on the shore of Lake Isolt at 3,800 feet early in January, 1912 ; and at Entebbe at the end of the following May. 32. Hemipimpla umbraticula, sp. 11. Exactly like the last species in superficial facies and coloration ; but with the head cubical, the vertex very broad and temples hardly narrower than the internally entire eyes ; antennae filiform, deep black and not setiferous, with their base immaculate and apex red. Thorax with notauli wanting and metanotum very sparsely punctate, not centrally sulcate, with elongate spiracles. Abdomen finely punctate and subfusiform ; basal segment much longer than apically broad with its disc glabrous and laterally bicarinate ; terebra fully as long as Avhole body. Posterior legs dead-black ; wings nigrescent, the front ones wdth an indefinite transfascia, from beyond the black stigma to anal nervure, subhyaline ; hind wings pale only at base of radial cell ; nervellus not intercepted below centre. Length 15 mm., ? only. The type was captured m the Bigona Forest at Unyoro in L'ganda at 3,700 feet by Neave, at the beginning of December, 1911, and is in the British ]\Iuseum. 108 ICHNEUMONIDAE. 34. Hemipimpla superba, Szepl. Erythropirnpla supcrha, Szepl., Sjostedt's Kilim.-Meru Exped. 1910, p. 79, pi. V, fig. 7, ?. A red-j^ellow species with fulvous abdomen and black hind legs, length 11 mm., and terebra as long as body ; the wings are nigrescent throughout with only a single subapical pale fascia and the nervellus intercepted below its centre. The type alone AA'as found near Usambara in June, and I have seen nothing lilte it.* TROMATOBIA, Thomson. Opusc. Ent. 1412; (?) Forster, Verb. pr. Rheiul. 1868, p. 164. Head with the cheeks very short ; elypeus convex, with its disc not deplanate and its apex truncate or very slightlj'- emarginate ; eyes emarginate, with their internal orbits pale ; vertex not centrally retused ; antennae filiform. Thorax with distinct notauli ; metathoracic spiracles circular and areola not complete ; scutellum often pale-marked. Abdomen with narrow epipleurae ; tarsal cla^s of ? basally lobate. Wings with the disco-cubital nervure subgeniculate before its centre ; nervellus intercepted somewhat above its centre. TABLE OF SPECIES. (8) 1. Legs mainly red ; femora not at all black-lined.

It seems certain that Szepligeti misiuiderstood the present genus (as was indicated by Schulz in Zool. Annalen, 1911, p. 31) and that this species, with black head and thorax, fulvous abdomen and " Fliigel ohne iVi-eola," does not belong to this genus which its author erroneously considered distmct from Erythropimpla, Ashm.
